Introduction

Mathematics is a broad topic which covers many aspects including: arithmetic, algebra, geometry, measurement, calculus, statistics, and trigonometry. There are lots of websites about mathematics. Many of these websites will cover more than one aspect of mathematics, so remember that if a website mentioned below is in one topic, it may also be useful for another that it is not listed under.

Arithmetic

Arithmetic covers basic calculations including addition, subtraction, multiplication, division, fractions, and percentages.

Math is fun

This site offers straightforward explanations and can be searched either using the topic buttons or keywords in the search bar.

  • Select the Numbers button for information and exercises.

  • Then go down the page to find information on topics like Decimals or Binary Digits.

  • Or, use the search function to enter the keyword 'Algebra' to bring up articles on the topic.

Tips: Search words, or keywords, are the most important words in our question. You can leave out small words like ‘the’ and ‘of’ and just choose the main ones, eg 'Algebra'. We can always change our keywords or add more if we need to.
